The first serial number of a Type N produced was 8604.
Are all Type N engines the same?
The short answer to this question is no, over the years Ronaldson Bros. & Tippett refined their design of the Type N and made changes.

Reasons WHY Ronaldson Tippett Engines Lead for Quality, Reliability, Long Life and Efficency under the most Arduous Conditions!
On of the many features of the Engine is the specially designed Cylinder Block.
Cast separately from the crankcase and cylinder head, it can be easily replaced when rendered necessary after many years of arduous work, or by negligence.
Such a replacement costs only a few pounds and can be done by anyone in about half an hour . . . no costly re-bore or weeks of waiting.
Cylinder after machining, is honed true to one half-thousandth of an inch, giving an unusually hard and glass-smooth surface.
Silchrome steel valves are used, ensuring very little grinding after many years of service.
Tappets and Valve stems work in an oil sprayed, dust-proof chamber, cover of which is removed in the photo on the left.
All castings are placed in an oil-fired furnace where they are subjected to special heat-treatment for twelve hours. This frees them of all stresses.
No further distortion can take place after machining, as often happens with non-heat-treated castings.
Distortions mean undie pressure on wearing parts with shorter life and lower efficiency.
Ronaldson Tippett engines are, we believe, the only power units produced with all castings heat-treated
The Governor is carried on the Pinion driving the Magneto and is of the very simplest design.
Governor weights are made from special steel, case-hardened to eliminate wear.
Governor is totally enclosed, running in an oil bath, but can quickly got at by removing a small place.
This Governor is remarkly quick and efficient in its action.
Constant speeds are definitely assured under any conditions whatever – a highly important feature for all work.
Speed can be varied by regulating a thumb screw while engine is running.
An Investment that will Pay lifetime dividends!
Piston and Connecting Rod
The Piston (A) is in special alloy cast iron, finished to a half-thousandth of an inch.
The three rings – two compresion (I) and one oil (J) – are of the latest design, ensuring perfect compression and long life.
The Connecting Rod (B) is drop-forged in special high-tensile steel, heat-treated. Gudgeon Bush is in phosphor bronze.
Gudgeon Pin (C) is of floating type, case=hardened and ground true to a half thousandth of an inch.
Big-End Bearings (F) are die-cast, giving long life with a minimum of attention.
The use of Tapered Roller-Bearings is an important advance in design, enabling a very compact engine to be built, and ensuring the elimination of all Main Bearing Troubles.
Highest efficiency is assured because friction is reduced to almost nil, and crankshaft wear at the Main Bearings is avoided.
Working parts are not only totally enclosed, protecting them from dust and grit, but they operate in an oil or oil-vapour bath.
Lubrication is entirely automatic throughout, with only one oiling point.
Every working part on the engine is lubricated efficiently and positively.
Complete reliability and the longest possible life is thus assured even under the worst working conditions.
Special Oil Seals, fitted to the crankshaft, prevent oil leaks and oil throwing off from the flywheel.
This is but one of the refinements which place the Ronaldson Tippett engine definitely in the front rank of quality engines.
Cams are ground on a special profiling machine ensuring true timing and high engine efficiency.
All Gears are, of course, machine-cut and as they run in the constant oil bath, long life and silent operation are assured.
The Camshaft Gear is in phosphor bronze, and both Pinions are in special steel.
The drop-forged Crankshaft is made of the highest-quality steel, not only ensuring the greatest strength, but the longest wearing life.
After heat-treating it is machined and finally ground true to a half-thousandth of an inch.
Balance weights are integral with the web, giving wonderfully sweet, vibrationless running, with consequent long life to the wear parts of the Engine.
Modern Assembly Methods
Ensure a Precision-Built Product!
This is our Petrol Engine Bay, where this type of Engine is built under standardised progressive assembly methods.
Rigid inspection at every stage of the manufacture of the Engine assures that reliability for which Ronaldson Tippett engines are famed throught the land.
Amazing Fuel Economy!
Patented Petrol-Kerosene Attachment Ensures Efficient Running on Power Kerosene.
This illustrates the special fuel tank with which the Petrol-Kerosene Engines are equipped.
The main container is for power kerosene, the small compartment beneath holds enough starting petrol to ensure a sufficiently hot engine for changing over to kerosene.
Some of its advantages are:
1. Extremely simplicity – change over to kerosene entirely automatic.
2. Once engine is set in motion there is no necessity to make any further adjustments.
3. The design (which is a Ronaldson Tippett Patent) provides splendid combustion – much better than is the case with other Kerosene Engines.
4. No loss of power on kerosene.
5. Cuts running cost practically in half.
6. Will run on straight petrol with equal satisfaction.
The exceptional results secured with this Ronaldson Tippett Patent is a revelation not only to the average user but to engineers of wide experience.
